Question OEM dual vs single side aftermarket exhaust

So, if/when I decide to go exhaust shopping which is better? Weight savings says single side exhaust (+ header). But I have seen full systems with dual as well. I have no real preference other than I would like the sound to be more pronounced than factory. My direction is headed in Brocks alien head 2. But, they are not out yet for my bike. However, I toyed with the idea of the M4 exhaust (which I have loved in the past!) And then Muzzy and D&D and so on and so forth... The full system brocks setup looks impressive though and from what I am understanding highly sought after for my bike (zx-14R). But, single side or dual would be my only question. And, If I decided to go with the dual slip ons, what would I be losing performance wise. Oh, I am not taking this to any track. This is a street application only. the "for track only" rhetoric.

A 4 into one typically gives more power providing the cannister isn't too restrictive.
The design offers several advantages in terms of using collector length and design to optimize scavenging. Not to mention weight savings.
We've had excellent results on the first gen ZX14's that we've used the Brocks Alien Head on.
One caveat, they are loud.

And there lies my question. For the few videos that I've seen, single side "full systems" are what have been used. And dual "slip on's" where used in dual applications. When I know that they make dual "full systems". I was curious why that was. Anyway, I'm not trying to make this complicated I just want to know what is preferred. I have no intentions on getting any fuel management system right now so no dyno tuning will be required. For now, I just want to change the exhaust.

The Brocks IS loud as . I have always liked Muzzy on Kawis in the past. I got a good deal on a full s/s Muzzy and I'm running it on the Busa. JoeBusa and I came within .5 hp on the dyne minutes apart. He is running the Alien Head on his. Dragging legs at the track the pipe roasts his right leg. It does sounds good, but it is very loud and raspy IMO. I would always choose to ditch the second can when possible.

Hey Patrick, then I guess the Brocks Alien Head 2 full system is going to be my choice. I was wondering did you have any "inside" information on the possible release date? I called Brocks and they say "soon" and want me to order the system and wait for them to ship it out. Which isn't a problem so much as I would prefer to order it minus the shipping from you or someone local.

Question Slip on vs full system revisited...

I was just on the Brocks website and a mere two seconds from completing my order (a nearly gut wrenching two thousand dollar order), when it hit me. Would I really be reaping the benefits of getting a full system or should I go with the slip-ons? Now, before the bashing begins let me explain a few things. I will almost certainly never put this behemoth on anybody's track or dragstrip. My days of the overly aggressive "routes" have come to a close. And more importantly, spending 2 grand on horsepower I will never use seems a little ridiculous to me (, I sound old). Now, what does concern me is the potential damage done to the engine when any upgrade is performed on a bike. I.e. engines running lean/rich and so on. That said, would it be neccessary to implement a power commander and/or a performance air filter with just slip-ons?
